Detect RTL text in events and adjust the text rendering (#6994)

* Add `TextDirection.detect` to check the overall LTR or RTL direction of texts

* Calculate if the contents of events have a different direction than the layout to reverse the layout direction if needed.

LTR content, RTL text -> mismatched direction, reverse.
RTL content, LTR text -> also mismatched, reversed too.

* Measure text in `measureLastTextLine` based on its direction, not the layout's,
to avoid some issues with incorrectly calculated free space.

* Tweak the paddings in `TimelineEventTimestampView` a bit if the layout and text directions don't match

* Update screenshots
